While the exact chemical treatment plan will be determined by a local water expert after performing an analysis of a water sample, there are some chemicals that are commonly used to treat boiler water.
Water quality is of the utmost importance in proper and safe boiler operations. An improperly treated feedwater system can result in the scaling of the boiler internals, safety equipment and auxiliary piping.
A condensing boiler can condense the water vapour in the flue gases and withstand the corrosive and acidic qualities of the flue gas condensate. Although most boilers can condense the flue gasses, only boilers that have heat exchangers constructed from materials able to withstand the corrosion should be used in condensing application. Condensing boilers with primary and secondary heat exchanger do not work well as they are not able to fully condense and defeat the purpose of using a condensing boiler. Also, boilers with this arrangement are prone to condensation in the primary heat exchanger at lower firing rate which can cause damage to the heat exchanger.
To prevent scale formation from low remaining levels of hardness which may have escaped treatment. Sodium phosphate is normally used for this, and causes the hardness to precipitate to the bottom of the boiler where it can be blown down.
The quality of the water used to produce the steam in the boiler will have a profound effect on meeting the objectives such as safe operation, maximum combustion and heat transfer efficiency, minimum maintenance and long working life.
In the operation of gas-fired steam/hot water boiler, it need continuous water supply to ensure the water volume in the drum. Once water shortage occurs, it will cause the boiler dry burning problem, which will further result in the boiler failure and other problems.
The thermal oil heater, also called organic heat carrier boiler, provides heat energy for production by heating the heat medium oil. It can realize the high-temperature and low-pressure heating without constant water supply. What are the characteristics of the thermal oil heater?
The gas-fired hot water boiler heats up quickly and has the high thermal efficiency. It is widely used in the heating industry and production. What are the maintenance methods of the gas-fired hot water boiler?
